I think I cant tell what it says

An equivalent expression of (33 x 66) - 3 is 2175.

The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations. P is for "parentheses," E is for "exponents," M is for "multiplication," D is for division, A is for addition, and S is for subtraction.

Given:

We have an expression,

(33 x 66) - 3.

Solving further by using PEMDAS,

33 x 66 = 2178

Now,

(33 x 66) - 3,

= 2178 - 3

= 2175

Therefore, the solution is 2175.

Making 'b' the subject of formula gives b = a² - 6

It is important to note that the subject of formula is described as a variable that is made up to stand alone in an equation.

The subject of formula is the variable that is worked out on on side of the equation sign.

From the information given, we have the equation;

a = [tex]\sqrt{(b + 6)}[/tex]

To make 'b' the subject of formula, we take the following steps;

Find the square of both sides, we get;

a² = [tex](\sqrt{(b + 6)} ^2[/tex]

Cancel out the square, we get;

b + 6 = a²

collect the other terms on one end of the equation, we have;

b = a² - 6

Hence, the equation is b = a² - 6

Answer:

r = 8.5 inches

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi *r

17 pi = 2 * pi *r

Divide each side by 2 pi

17 pi / ( 2pi) = 2 * pi r/ ( 2 pi)

17/2 = r

8.5 = r

The answer is 8.5 inches.

Answer:

(262, 690)

Step-by-step explanation:

Given that :

Mean score = 476

Standard deviation, s = 107

2 standard deviations above and below the mean :

Mean ± 2s

Hence,

2 standard deviations below :

476 - 2(107)

476 - 214 = 262

2 standard deviations above

476 + 2(107)

476 + 214 = 690

Answer:

Width: 16 in.,  Length:  18 in.

Step-by-step explanation:

Consecute even/odd problems seem a bit weird at first.

You choose a variable to represent the first integer, say  n .  Assume it's even (no symbolic way to tell!).  If  n  is even, then the next consecutive integer is  n + 2.  You add two because you want to skip one integer.

Width:  n

Length:  n + 2

Area is length multiplied by width, so

[tex]n(n+2)=224\\\\n^2+2n=224\\\\n^2+2n-224=0\\\\(n+14)(n-16)=0\\\\n+14=0 \text{ or } n-16=0\\\\n=-14 \text{ or }n=16[/tex]

The negative solution makes no sense, so use n = 16

Width: 16

Length: 18

Answer:

C. (4 , 3)

Step-by-step explanation:

We are given a system of equations and are asked to find its coordinate value.

To solve, we can keep in mind that both start with y, therefore meaning that we can replace one of the y's with one of the equations.:

[tex]y=\frac{1}{4}x+2\\y=x-1[/tex]

[tex]\frac{1}{4}x+2 = x-1[/tex]

Let's try to get x alone, first subtract 2 from both sides:

[tex]\frac{1}{4}x=x-3[/tex]

Now subtract x from both sides:

[tex]-\frac{3}{4}x=-3[/tex]

Now since the denominator is 4, multiply both sides by 4:

[tex]-3x=-12[/tex]

Lastly, divide both sides by -3 to get x :

[tex]x=4[/tex]

Now that we know x is 4, we can substitute 4 for x in both equations:

[tex]y=\frac{1}4(4)+2\\y=(4)-1[/tex]

[tex]y= 3\\y= 3[/tex]

Y is equal to 3, therfore, our coordinate value is C. (4,3)

Answer:

The perimeter is 36 cm

Step-by-step explanation:

Given;

area of the rectangle, A = 81 cm²

let the Length, = L

let the breadth = b

Perimeter, P = 2L + 2b

Area, A = Lb = 81

[tex]L = \frac{81}{b} \\\\P = 2(\frac{81}{b} ) \ + \ 2b\\\\P = \frac{162}{b} \ + \ 2b\\\\P = 162(b^{-1}) \ + \ 2b\\\\minimize \ the \ perimeter \ to \ obtain \ the \ critical \ points;\\\\P' = -162 (b^{-2}) \ + \ 2\\\\P' = \frac{-162}{b^2} \ + \ 2\\\\P' = \frac{-162 \ + \ 2b^2}{b^2} \\\\at \ critical \ points; P' = 0\\\\\frac{-162 \ + \ 2b^2}{b^2} = 0\\\\-162 \ + \ 2b^2 = 0\\\\2b^2 = 162\\\\b^2 = 81\\\\b = +/- \ \sqrt{81} \\\\b = +/- \ \ 9\\\\[/tex]

[tex]since \ the \ breadth \ will \ be \ positive \ ; b = 9 \ cm[/tex]

L = 81/9

L = 9 cm

The perimeter = 2 (L + b)

                         = 2 (9 + 9)

                         = 2(18)

                         = 36 cm

Answer:

B. AC = 22, BC = 22, AB = 44

C. AC = 30, BC = 30, AB = 60

Step-by-step explanation:

B.

[tex] radius \: \overline {OR} \perp chord \: \overline {AB} [/tex] at C. (given)

[tex] \therefore AC = BC[/tex] (perpendicular dropped from the center of the circle to the chord bisects the chord)

[tex] \therefore 2x - 6 = x + 8[/tex]

[tex] \therefore 2x - x= 6 + 8[/tex]

[tex] \therefore x= 14[/tex]

[tex] AC = 2x-6=2(14)-6=28-6= 22[/tex]

[tex] BC= x + 8=14 + 8= 22[/tex]

AB = AC + BC = 22 + 22 = 44

C.

[tex] radius \: \overline {OR} \perp chord \: \overline {AB} [/tex] at C. (given)

[tex] \therefore BC = AC[/tex] (perpendicular dropped from the center of the circle to the chord bisects the chord)

[tex] \therefore 7x-5=4x+10 [/tex]

[tex] \therefore 7x - 4x= 5 + 10[/tex]

[tex] \therefore 3x= 15[/tex]

[tex] \therefore x= \frac{15}{3}[/tex]

[tex] \therefore x= 5[/tex]

[tex] AC = 4x+10=4(5)+10=20+10= 30[/tex]

[tex] BC= 7x - 5=7(5)-5=35-5= 30[/tex]

AB = AC + BC = 30 + 30 = 60

Answer: 0.474 miles

Step-by-step explanation:

First find out how fast they can run per minute.

Phil runs 3/8 miles in 7 minutes:

Speed = Distance / Time

= 3/8 ÷ 7

= 0.0536 miles/minute

Joe runs 5/8 miles in 9 minutes:

Speed = 5/8 ÷ 9

= 0.0694 miles per minute

In 30 minutes, Phil will run:

= Miles per minute * Time

= 0.0536 * 7

= 1.608 miles

Joe will run:

= 0.0694 * 30

= 2.082 miles

Difference:

= 2.082 - 1.608

= 0.474 miles

Answer:

12.9x-9

Step-by-step explanation:

add 5.3x and 7.6x

Answer:

12.9x-9

Step-by-step explanation:

First you have to combine the like terms which are 5.3x + 7.6x= 12.9x. Then you just rewrite the equation 12.9x-9. You just leave the 9 by it self because there's no other like terms.

More examples -

5.3x+−9+7.6x

Combine Like Terms:

=5.3x+−9+7.6x

=(5.3x+7.6x)+(−9)

=12.9x+−

Step-by-step explanation:

The sum of any straight angle is 180 (Therom)

180 - (50 +35) =95

Answer:

2 21 degree angles

Step-by-step explanation:

An isosoles triangle has two congruent angles and every triangle's sum of interior angles equals 180 degrees. 138*2>180, so the 138 degree angle cannot be congruent to any of the other angles. Therefore:

180=138+2x

42=2x

21 degrees=x
